Just to tell you that it is working
I don’t know how to code. It is because of beaverbuilder or Smartslider. Because if it is from beaverbuilder I can send them a bug report. If else I would tell you if you can do it and I would recommend you to advertise/talk about your pluggin to its community as it is growing fast, could be interesting for you like here https://www.facebook.com/groups/beaverbuilders/, a good a feature rich slider like yours could work well if well suported in BB.
